Input-output norms require imported inputs to conform to prescribed proportions and be used in the declared export product.

Standard Input-Output Norms prescribe the input ratios for manufacture of Polyvinyl Butyral Resin, specifying Poly Vinyl Alcohol and N Butyraldehyde as required feedstocks with designated proportions per kilogram. The schedules require determination of input proportions and oblige applicants to ensure imported goods correspond to those actually used or required in the declared export product.
